Install Issue.

I have a 6 gb ide drive.
I try to install oBSD 2.5 I receive a "uid 0 on /: file system full" error
imediately after i type 'I' for (I)nstall.
I did the the fdisk thang so I have it partioned up into a 4gb and 2gb.
I also did the fdisk /MBR seeming how this disk is really messed up at the
moment.
It worked the first time through installing but it choked on extracting
the tar.gz set's to the disk. Ever since it's been hosed.
Any help would be appreciated,
Josh
